The aim of this study was to compare results of D1-plus vs D2 resections and to provide a literature review. Methods Patients who underwent upfront R0 gastrectomy for adenocarcinoma from 2000 to 2016 in three Institutions were selected using propensity scores and categorized according to lymphadenectomy. Statistical analyses were performed for the nodal harvest (LNH) and survival. Published literature comparing D1-plus and D2 was reviewed and analyzed according to PICO and PRISMA guidelines. Results Two matched groups of 93 D1-plus and 93 D2 resections were selected. LNH was significantly greater in D2 vs D1-plus dissections (mean 31.2 vs 27.2, p 0.04), however LNH distribution was similar. The cumulative incidence curves for overall survival, disease free and disease specific events did not report significant differences, however Cox regression analysis disclosed that total gastrectomies (HR 1.8; 95% 1.0-2.9), advanced stages (HR 5.9; 95% 3.4-10.3) and D1-plus nodal dissection (HR 2.1; 95% 1.26-3.50) independently correlated with disease free survival. Literature review including 297 D1-plus and 556 D2 lymphadenectomies documented LNH in favor of D2 sub-group (SMD -0.772; 95%CI -1.222- -0.322). Conclusion D2 provided greater LNH than D1-plus dissections; prospective studies should aim to investigate long-term survival of D1-plus lymphadenectomy.Background Psychological and behavioral correlates are considered important in the development and persistence of obesity in both adults and youth. This study aimed to identify such features in youth with severe obesity (BMI ≥ 120% of 95thpercentile of sex-specific BMI-for-age) compared to those with overweight or non-severe obesity. Methods Youth with BMI ≥ 85th percentile were invited to participate in a prospective research registry where data was collected on attributes such as family characteristics, eating behaviors, dietary intake, physical activity, perception of health and mental well-being, and cardiometabolic parameters. Results In a racially/ethnically diverse cohort of 105 youth (65% female, median age 16.1 years, range 4.62-25.5), 51% had severe obesity. The body fat percent increased with the higher levels of obesity. There were no differences in the self-reported frequency of intake of sugar sweetened beverages or fresh produce across the weight categories. However, the participants with severe obesity reported higher levels of emotional eating and eating when bored (p = 0.022), levels of stress (p = 0.013), engaged in fewer sports or organized activities (p = 0.044), and had suboptimal perception of health (p = 0.053). Asthma, depression and obstructive sleep apnea were more frequently reported in youth with severe obesity. The presence of abnormal HDL-C, HOMA-IR, hs-CRP and multiple cardiometabolic risk factors were more common among youth with severe obesity. Conclusions Youth with severe obesity have identifiable differences in psychosocial and behavioral attributes that can be used to develop targeted intervention strategies to improve their health.Background Members of the genus Proteus are mostly opportunistic pathogens that cause a variety of infections in humans. The molecular evolutionary characteristics and genetic relationships among Proteus species have not been elucidated to date. In this study, we developed a multilocus sequence analysis (MLSA) approach based on five housekeeping genes (HKGs) to delineate phylogenetic relationships of species within the genus Proteus. Results Of all 223 Proteus strains collected in the current study, the phylogenetic tree of five concatenated HKGs (dnaJ, mdh, pyrC, recA and rpoD) divided 223 strains into eleven clusters, which were representative of 11 species of Proteus. Meanwhile, the phylogenetic trees of the five individual HKGs also corresponded to that of the concatenated tree, except for recA, which clustered four strains at an independent cluster. The evaluation of inter- and intraspecies distances of HKG concatenation indicated that all interspecies distances were significantly different from intraspeapid and inexpensive means of identifying Proteus strains. The identification of Proteus species determined by the MLSA approach plays an important role in the clinical diagnosis and treatment of Proteus infection.Background Hepatic adrenal ectopia is a common clinical diagnosis, whereas adrenal tumors developed from hepatic adrenal ectopia are rare. Hepatic adrenal tumors are easily misdiagnosed as hepatic carcinoma and frequently treated by unnecessary operations. Case presentation A 50-year-old female patient was hospitalized due to B-ultrasonic detection of "right focal liver lesions." After hospitalization, enhanced CT examination was performed. A 2.2 cm × 1.8 cm tumor was found in the seventh section of the right liver, as indicated by obvious enhancement of the arterial phase and low density during the portal vein and delay stages. Enhanced MRI examination detected a 2.0 cm × 1.8 cm tumor on the right liver, which was considered a "primary hepatic carcinoma". Selleck GSK3787 The patient was treated by open hepatectomy and recovered well after the operation. The postoperative pathological diagnosis was hepatic adrenal adenoma. No relapse was observed through the 1-year follow-up visit. Conclusions According to imaging manifestations, pathological immunohistochemical treatment, alpha fetoprotein (AFP) and clinical features, hepatic adrenal tumors should be considered in the diagnosis of hepatic carcinoma to prevent misdiagnosis. Hepatic adrenal tumors should be ruled out during the diagnosis to avoid unnecessary operation.Background Injuries are of growing public health concern in China, and the trends of urban-rural injury mortality disparity for the last decade are still being explored. This study aims to analyze trends in injury mortality disparity between urban and rural areas of China by region, sex, and age from 2010 to 2016. Methods Using data from the Disease Surveillance Points system (DSPs) collected by the Chinese Center for Disease Control and Prevention (CDC) from 2010 to 2016, injury age-standardized mortality rates (ASMRs) and rate ratios (RRs) were calculated for different groups. Chi-square tests were used to compare differences in rates between urban and rural residents. The time trends of injury ASMRs were assessed via the annual percentage change (APC), and RRs were used to analyze urban-rural mortality disparity. Results The crude injury mortality rate of rural areas was 1.5 times higher than that of urban areas. The urban-rural RR of injury ASMR decreased from 1.8 to 1.5 (APC = 5.0%) over time, from 2.0 to 1.
